Spring balance
Temporarily turn off the power, and keep the barrier arm at 40°–45° from the horizontal
plane to check whether the barrier arm can be still and balanced. If not, adjust the spring
tightness. For details, see "3.4 Adjusting Barrier Arm Length."
Display of control board
When the Barrier works, check whether the control board LED displays the normal angle
value. If an error code is displayed, find the cause and solve the problem.
